JOHN PRAY, OF LYNN, MASSACHUSETTS, ASSIGNOR TO CUTOHEON dv JOHNSON, OF SAME PLACE.

MACHINEFOR `BEATING OUT BOOT OR SHOE SOLES.

SPECIFICATION forming part of Letters Patent No. 367,927, dated August 9, 1887.

Application filed May 3l, 1887. Serial No. 239,8l9. (No model.)

` .To @ZZ whom, it may concern:

y the same.

Be it known that I, JOHN PRAY, of Lynn,

in the county of Essex andA State of Massa-` chusetts, have invented a new and useful Improvement in Machines for Beating Out Boot or Shoe Soles, of which the following, taken in connection with the accompanying` drawings, is a specification. f

`My invention relates to machines for beating out the solesof boots or shoes, and has for its object the adaptation of such machines' to the beating out or molding and shaping of the soles of turned sewed slippers, which heretofore has been done exclusively by hand,and also to obviate the objections made to themachines now in common use--viz., thefgreat liability of breaking. the iron last upon which `the boot or shoe is placed, due to the 'unequal pressure given to the sole on account of variations in the thickness thereof-and to rena der it practical to beat out the soles of boots or shoes without removing them from the wooden lasts upon which they are built; and it consists in certain novel features of construction, arrangement, and combination of parts, which will be readily understood by reference t0 the description of the drawings and to the claims to be hereinafter given.

' Figure l of the drawings .is a side elevation of a machine embodying my invention. Fig. 2 is a front elevation of the upper portion of Fig. 3 isa vertical section of a portion of the upper part'of the machine on line a' w on Fig. 2, and Fig. 4t is a similar section illustrating another formof construction.

In the drawings, A A are the side -frames of the machine, connected together by the girt B and tie-rods at a and b, and having set therein the two upright rods G C', upon Vthe upper ends of which is fitted and iirmly secured by the nuts c c the cross-head D.

E is a plate fitted to slide vertically on the rods C C', and having pivoted to its under side at the center of its length the togglelink F, to the other end of which are pivoted th-e toggle-link Fl and the connecting-rod G, which is connected at its rear end to the crankl H, formed in the shaft H', mounted in bearings A on the framesA. The lower end of the toggle-link F is pivoted to the upper side of the girt B, as shown in dotted lines in Fig. 1. The shaft H has mounted thereon the gear-wheel l, with which the pinion J on the shaft J meshes to impart thereto a rotary motion as said shaft J is revolved by the action of a belttnot shown) upon the pulley K. L is a plate pivoted by itsr center upon the rod C', and resting upon 'the upper surface of the plate E and movable vertically therewith, while at the same time it maybe revolved about said rod C by the operator at will.

Upon each end of the plate L is mounted a shoe-supporting jack, M, the center of which is at a distance from the center of the rod C' shoe will be toward the front of the machine,

or toward the left hand of Fig. 1.

To the under side of the cross-head D, and atpthe center of its length, is secured by the bolt N, Vprovided with a milled head, N', the block O, provided with two upwardly` projecting lips, O O',which embrace the edges of the lower ribs of said cross-head, asshown in Figs. l and 2. A rubber cushion, l?, is insert-ed between the under side of the crosshead D and the block O, so as to render said block yielding to a limited extent, to compensate for varying thicknesses of soles and to prevent too great a pressure thereon. y

R is a mold or die for 'shaping or beating out the sole, tted to a dovetailed slide in the undersurface of the block O, and adjustable endwise therein by means of the set-screw d, as shown in Figs. 1, 3, and et.

To compensate for varying thicknesses at the two ends of the'same sole, or slight variations in the'heights of the heel ends of diierent lasts of the same size, I mount the shoeroo I M', or between the block O and the plate O2, one upon each side of the pivot e, as shown, respectively, in Figs. 8 and 4.

Vhile I prefer the construction shown in Figs. 1, 2, and 3, it is obvious that the same result may be accomplished by the construction shown in Fig. 4, and therefore I do not wish to be limited to a pivoted jack and fixed mold as against a pivotcd mold and a nonpivoted jack.

The jack M is provided with a pivoted pin, Il., to enter the hole in the heel end of the ordinary wooden last, and a toe-rest, S, adjustable on the arm S, to adapt it to lasts of different lengths, and the lower end of the pi voted pin 71. is pressed toward the heel end of the jack by the spring fi, as shown in Fig. 3, the effect of which is to hold the toe of the last iirmly in contact with the toe-rest S, in a wellknown manner.

The operation of my invention is as follows: A boot or shoe being placed while on its wooden last upon the jack, and the crank-shaft being revolved, the toggle-links will be brought into a perpendicular position, thereby moving the plates E and L, with the jack M, upward till the sole of the shoe is pressed into close contact with the under` surface of the mold or die R, and has imparted thereto the desired shape by being subjected to an even pressure over the whole length of said sole, even though the toe end of the sole may be thicker than the heel end in one shoe and in the next shoe the heel end may be thicker than the toc end, because of the fact that the last or the mold is free to rock upon its pivot when the pressure between them is greater at one end than the other.

The machine illustrated is a power-1nachine to be driven by a belt applied to the pulley K, which may be a friction-pulley of any wellknown construction, to be controlled by a treadlc, (not showin) but it is obvious that, if desired, the toggle-links F and F' may be straightened,and thus move the jack upward by foot-power; or the shaft J may be revolved by hand without affecting the principle of my invention.

\Vhat I claim as new, and desire to secure by Letters Patent of the United States, is-

1. rlhe combination, in a beating-out machine, of a jack supported by a transverse pivot or axis and two springs, arranged one upon each side of said pivot, so that it may be vibratcd in the direction of its length, and thus automatically accommodate itself to any inequalities in the thickness of the sole or in the general level of the tread-surface of the last, and a non-vibrating mold or die for shaping the sole.

2. The combination, in a beatingont inachine, of a jack mounted upon a transverse pivot or axis and two springs, arranged one upon each side of said pivot, so that it may be vibratcd about said axis when an unequal pressnre is applied thereto, and thus automatically accommodate itself to any inequalities in the thickness of the sole or in the general vlevel of the tread'surface of the last, means, asset forth, for supporting an ordinary wooden last thereon, a non-vibrating mold or die, and means, substantially as described, for causing said jack and mold to approach each other.

In testimony whereof I have si gncd my name to this specification, in the presence oi'two subscribing witnesses, on this 27 th day of May, A. D. 1887.

.iol-1N PRAY.
